Abstract

The invention provides a process for isolating tetrafluoroethylene polymer resin from aqueous dispersion produced by dispersion polymerization, comprising first freezing said dispersion to form frozen dispersion, then thawing said frozen dispersion to form thawed frozen dispersion, and then separating said resin from liquid of said thawed frozen dispersion.
